Prevention and Management of
Esophageal Variceal and Portal
Hypertensive Hemorrhage

Gastroesophageal Variceal
Hemorrhage
 Gastroesophageal variceal hemorrhage is one of
the major complications of portal hypertension
from cirrhosis
 Variceal hemorrhage occurs in 25-35% of
cirrhotics and accounts for 70-80% of UGIB in
these patients.
 Aprroximately 50% of cirrhotics will have varices
at the time of diagnosis
 7-8% develop de novo varices each year

Gastroesophageal Variceal
Hemorrhage
 The 1-year risk of a first variceal hemorrhage is
approximately 12% (5% for small varices and
15% for large varices).
 The 6-week mortality with each episode of
variceal hemorrhage is approximately 15 -20%,
 From 0% among patients with Child class A disease
to 30% among patients with Child class C disease.
 The 1-year rate of recurrent variceal
hemorrhage is approximately 60%.
Pathophysiology
Portal Venous Anatomy
Hepatic/Portal Blood Flow
 Blood accounts for 25-30% of the volume of the
liver
 Total Hepatic Blood Flow: Hepatic arterial and
portal venous blood flow
 Approximately 25% of the cardiac output
 Males: 1860 cc/min
 Females: 1550 cc/min
 Portal venous blood flow averages 1500 cc/min
 Normal portal venous pressure is 4-8 mmHg
Hepatic Lobular Anatomy
Pathophysiology
 Gastroesophageal varices are a direct
consequence of portal hypertension that, in
cirrhosis, results from
 Increased resistance to portal flow
 Structural (distortion of liver vascular
architecture by fibrosis and regenerative
nodules) and
 Dynamic (increased hepatic vascular tone due
to endothelial dysfunction and decreased nitric
oxide bioavailability).
 Increased portal venous blood inflow.

Primary Prophylaxis
 In view of the relatively high rate of bleeding
from esophageal varices and the high
associated mortality, an important goal of
management of patients with cirrhosis is the
primary prevention of variceal hemorrhage.
 As a result, all patients with cirrhosis should
undergo diagnostic endoscopy to document
the presence of varices and to determine their
risk for variceal hemorrhage.

Varices w/ Beta-Blockers?
 Multicenter, randomized, placebo-controlled trial
of timolol (non-selective beta-blocker) vs.

 Beta-blockers did not prevent the development of
varices and were associated with a higher rate of
serious adverse events
 In patients without varices, treatment with
nonselective beta-blockers is not recommended

Primary Prophylaxis for Variceal
Hemorrhage: Beta Blockers
 Non-selective beta-blockers preferred
 Beta-1 antagonism: reduced cardiac output
 Beta-2 antagonism: splanchnic vasoconstriction
 Goal of therapy to reduce portal pressure by 20%
or below 12 mm Hg
 Dose titrated to a resting HR of 55, or a 25%
reduction in baseline
 Initial dose propranolol 40 mg bid, Average dose
160 mg/day
 Up to 1/3 intolerant to side effects resulting in
discontinuation

ENDOSCOPIC VARICEAL BAND LIGATION
Endoscopic Variceal Band Ligation
Primary Prophylaxis for Variceal
Hemorrhage
 3 randomized controlled trials published
comparing band ligation to no treatment,
showing lower bleeding rates and mortality.
 Meta-analysis of 8 trial show banding superior
to beta blockers but no difference in survival
 One trial of band ligation and beta blockers: no
benefit
 Prophylactic sclerotherapy definitely of no
proven benefit, probably harmful.

Primary Prophylaxis for Variceal Hemorrhage:
Conclusions
 Propranolol is the most cost-effective treatment for
the prevention of initial variceal bleeding
 The documented benefits of prophylactic beta
blockers may be lost if discontinued due to a rebound
in bleeding/ mortality.
 Life-long beta blocker treatment is therefore
indicated
 Non-compliant patients may be better served by band
ligation therapy, although at substantially higher
costs ($1425 vs $4284)

TREATMENT OF ACUTE VARICEAL HEMORRHAGE
Treatment of Acute Variceal Hemorrhage
General Management:
 IV access and fluid resuscitation
 Antibiotic prophylaxis
 Correct coagulopathy
 Do not overtransfuse (hemoglobin ~ 7-8 g/dL)
 Empiric lactulose?
Specific therapy:
 Pharmacological therapy: octreotide, vasopressin +
nitroglycerin
 Early endoscopic therapy: band ligation
 Shunt therapy: TIPS, surgical shunt
Cautious Transfusion Improves Outcome
in Cirrhotics with Variceal Hemorrhage
 214 cirrhotics with UGIB randomized to restricted (Hgb
7-8 gm) or liberal transfusion (Hgb 9-10 gm)
 69% esophageal variceal 7% gastric variceal
 15% peptic ulcer
3% gastropathy
 Therapeutic failure occurred in 16% of restricted and
28% of liberal group (p<0.04)
 In subgroup with esophageal variceal bleed, the 6 week
survival without therapeutic failure was better in
restrictive group (84% vs 69%: p<0.02)
 38% in restrictive group required no transfusion vs 9%
in liberal group

Prophylactic Antibiotics Improve Outcomes in

PROPHYLACTIC ANTIBIOTICS IMPROVE OUTCOMES IN CIRRHOTIC PATIENTS WITH GI HEMORRHAGE
 The use of prophylactic antibiotics in cirrhotics
with GI hemorrhage has been shown by metaanalysis to reduce infection, increase survival, and
reduce recurrent hemorrhage (13 prospective
trials)
 Recommended antibiotics include oral
norfloxacin, ciprofloxin, ofloacin, and amoxicillin
clavulanate, ceftriaxone IV

 Octreotide:
 50 microgram bolus and 25-50 mcg/hr for up to 5
days (range 2-5 days)
 Vasopressin:
 Too dangerous for empiric initial therapy
 Contiunuous infusion 0.2-0.4 U/min up to 1.0 U/min
 Recommended only in combination with i.v. TNG: 1050 mcg/min
 Titrate TNG infusion to maintain systolic BP >90

Erythromycin improves visibility during
endoscopy for variceal bleeding
 Study involved 90 patients with cirrhosis who
had been vomiting blood due to variceal
bleeding during the previous 12 hours.
 The 47 patients randomized to the intervention
group received an intravenous bolus infusion of
125 mg erythromycin lactobionate in 50 mL
normal saline. The other 43 patients received
only the saline. (All patients also received
octreotide, esmoprazole, and ceftriaxone.)
Gastrointest Endosc 2010.
Erythromycin improves visibility during
endoscopy for variceal bleeding
 On multivariate analysis, erythromycin was the
only predictor of an empty stomach.
 As a result, the average time needed for
endoscopy was also shorter after erythromycin
(19 vs 26 min, p < 0.005).
 Physicians found that with erythromycin, they
could control bleeding by band ligation more
often (70% vs 49%, p < 0.04) and that hospital
stays were shorter (3.4 vs 5.1 days, p < 0.002).

TIPS in the Treatment of Variceal Hemorrhage
 TIPS is rescue therapy for recurrent variceal
hemorrhage
(at second rebleed for esophageal varices, at first
rebleed for gastric varices)
 TIPS is indicated in patients who rebleed on
combination endoscopic plus pharmacologic
therapy (10-20%)
 In patients with Child A/B cirrhosis, the distal
spleno-renal shunt is as effective as TIPS
(dependent on local expertise)
Early TIPS In Patients With Acute Variceal
Hemorrhage and HVPG > 20 mmHg (High Risk) May

 116 cirrhotics with acute variceal bleed
 Urgent assessment of wedged hepatic vein

 64 HVPG < 20 mmHg: routine therapy
 52 HVPG > 20 mmHg randomized to TIPS vs

 63 patients with cirrhosis and acute variceal bleeding
who had been treated with vasoactive drugs plus
endoscopic therapy
 Randomized to treatment with a polytetrafluoroethylenecovered stent within 72 hours after randomization
(early-TIPS group, 32 patients)
 Vs continuation of vasoactive-drug therapy, followed
after 3 to 5 days by treatment with propranolol or
nadolol and long-term endoscopic band ligation (EBL),
with insertion of a TIPS if needed as rescue therapy
(pharmacotherapy–EBL group, 31 patients).

 The 1-year actuarial probability of remaining free of this

group versus 97% in the early-TIPS group (P<0.001).
 Sixteen patients died (12 in the pharmacotherapy–EBL group

MANAGEMENT OF GASTRIC VARICES
Management of Gastric Varices
 Gastric varices that are continuous with
esophageal varices and extend along the
lesser curve (GOV1) should be treated in the
same way as esophageal varices
 In patients with isolated fundal varices (IGV1),
splenic vein thrombosis should be
investigated. If present, treatment consists of
splenectomy
 Cirrhotic patients bleeding from gastric fundal
varices require specific treatment

Prevention of Recurrent Bleeding TIPS
vs. Drug Therapy
 91 Childs-Pugh class B/C cirrhotic patients
who survived first variceal hemorrhage
 Randomized to TIPS(47) vs propranolol
plus isosorbide-5-mononitrate(44)
 Followed for 2 years
 Assess hepatic encephalopathy, recurrent
variceal hemorrhage, costs, number of
medical interventions, and survival
